I also get hacked off with singers who simper onto their feet and say "I'd like to sing a Martin Carthy song or a Christy Moore song, and then sing a perfectly recognisable traditional song. This was summed up for me beautifully when I was at a club in London where a young woman said, "I'd like to sing a song I got from Martin (first name terms); she then sang The Barley Straw. I was in a bit of a bad mood (I think Thatcher had just won a third term), so I said "didn't Harry Cox sing that?"
She replied, "Oh, does he; did he get it from Martin too?"

I trust you put her right then, Jim?
